英文摘要	In terms of the problems of insufficient interia supporting capacity of the system and loss of stable performance of grid frequency caused by increased wind power grid-connected capacity, virtual synchronous generator technology to simulate the operation characteristics of synchronous generator has become an effective solution. In this paper, the direct-drive permanent magnet wind turbine, one of the mainstream wind farm models, is taken as the research object, and a virtual synchronous control strategy is introduced into the grid-connected control to improve the equivalent inertia of the direct-drive permanent magnet wind turbine and make it deliver smooth power to the grid. The spare capacity is provided by the coordinated control of overspeed and pitch change of the unit itself, and the active power output is increased through the inertia response control link of the virtual synchronous generator, thus improving the primary frequency modulation capability of the system. The simulation results show that the coordinated control strategy proposed in this paper can make full use of the load shedding operation of wind turbines and the virtual synchronous generator technology andeffectively improve the frequency stability and intertia support effect of the grid-connected system, contributing to the safe and stable operation of the power system. © 2019 IEEE.
